Lewiston Historic District

Why it's listed
Lewiston Historic District covers the old center of a gold mining town in northwestern Trinity County, California. A one-lane bridge over the Trinity River leads into the Deadwood and Turnpike Roads intersection, where the store, butcher shop and houses cluster. The district runs about half a mile and holds 16 contributing buildings and structures, plus a bridge. Gabled roofs, wood construction, board and batten siding and front verandas are common, with a few Greek Revival details. Lewiston was founded in 1853 on mining and ranching and became a supply, transport and news center for miners. Olney Phillips, who ran a toll bridge and ferry and built a house in 1875, is among the figures tied to its buildings. The period of significance ends around 1925, when the town declined. It revived only in the 1950s with Trinity Dam, and development shifted to a new town to the east, leaving the old center largely unchanged.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
